A method is described to determine the time of death of elephants. This is accomplished by analysis of the radionuclides 14C, 90Sr and 228/232Th in known samples of ivory, and in samples of unknown age. The reliability of this method is considerably increased by multi nuclide analysis.
一种用于确定大象死亡时间的方法被描述出来。这是通过分析已知象牙样本中的放射性核素 14C、90Sr 和 228/232Th 以及未知年龄的象牙样本来实现的。通过多核素分析，该方法的可靠性得到了极大提高。
